AR027150MR-2-R

Overview

The AR027150MR-2-R is an electromagnetic receiver speaker manufactured by PUI Audio, Inc. It features a top port design with a round shape and operates at a nominal impedance of 150 Ohms. The component has a power rating of 15 mW and delivers a sound pressure level of 118 dBA at a resonant frequency of 650 Hz. Its operational frequency range extends from 20 Hz to 10 kHz. This device is designed for applications requiring high acoustic output in compact spaces.

Feature Summary

• High sound pressure level output for clear audio signaling
• Top port configuration for directed sound projection
• Electromagnetic transduction mechanism
• Compact round form factor suitable for space-constrained designs

Applications

• Medical equipment audio indicators
• Industrial control panel alerts

Procurement Notes

Verify the specific ordering suffix and packaging details against the official manufacturer datasheet before procurement. Confirm that the 150 Ohm impedance matches the target circuit requirements. Ensure the 15 mW power rating is sufficient for the intended drive conditions. Check RoHS compliance status if required by project specifications. Validate the top port orientation relative to the enclosure design.

Selection Notes

Select this component when high sensitivity is required within a small footprint. The 150 Ohm impedance may necessitate specific driver circuits compared to standard low-impedance speakers. Consider the 650 Hz resonance peak for tone matching. Evaluate the 118 dBA SPL capability against ambient noise levels. Ensure the physical dimensions fit the available mounting area.
